#3164

Se dau n, reprezentând numărul de elevi apoi, pe câte un rând, datele fiecărui elev: codul (număr natural de maxim 4 cifre), media la informatică (număr natural de la 1 la 10) și numărul de absențe. Definiți un tip structură pentru a putea memora datele unui elev și rezolvați cerințele:

a) memorați datele tuturor elevilor într-un vector de structuri de tipul definit;
b) afișați numărul de elevi cu media 10
c) afișați media clasei (se va afișa doar partea întreagă a ei).
d) afișați primii doi elevi după absențe (elevii cu cele mai multe absențe). Dacă sunt mai mulți elevi cu același număr de absențe se afișează în ordine crescătoare a codului. Dacă sunt mai mult de doi elevi număr maxim de absențe se afișează doar doi.
